IMPROVEMENT IN EEDSZFOR MUSlCAL INSTRUMENTS.A

Specification forming part of Letters Patent No. 193,192., dated July17, 1877-; application filed June 11, 1877.

To all whom 'it may concern Be it known that I, WILLIAM SPETH- MANN, ofthe city, county, and State of New York, have invented a new and usefullmprovement in Musical Reed, of which the following is a specificationFigure lis a front 4view of one of my improved reeds. Fig. 2 is-a detailsection of the same, taken through the line .fr x, Fig. l.

Similar letters of reference indicate correspending parts.

The object of this invention is to furnish an improved reed for toytrumpets and other reed musical instruments, which shall be neater andsimplerin construction, and less expensive in manufacture than whenconstructed in the usual way.

The invention consists in a musical reed, in which the reed or reeds isor are cut out of the body of the plate, so as to be in one piecetherewith, and having corrugations in the said plate, as hereinafterfully described.

A represents a piece of thin sheet brass or 'other suitable metal, ofany desired shape and size, as the particular instrument in which thereed is to be used may require.

a1 is the reed, which is formed by slitting the plate A along two sides,and one end of l so as to give any desired tone.

the reed al, as shown in Figs. l and 2. The reed al may be varied inlength and breadth rJhe plate A has a corrugation, a2, formed in itaround the edge of the reed al to withdraw the edge of the plate A fromthe edge of the reed al, so that the said reed can vibrate withouttouching the edge of the plate A.

The plate A has a corrugation, a3, formed in it around its edge tostiften it, and enable it to be made of sheet metal suciently thin toserve as a musical reed.

I am aware that it is not broadly new to construct a musical reed andsupporting'plate of one piece of metal.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 'A musical reed in which the reed or reeds al is orare cutout of the body of the plate A, so as to be in one piecetherewith. and having the corrugations a2 and a3 formed in the saidplate, substantially as herein shown and described.

WILLIAM SPETHMANN.
